Abstract
Aim of the study - to investigate the effect of erythropoietin (EPO) on the absorption and NBT-re-ducing capacity of neutrophils isolated from the blood of preterm neonates (PN) in vitro. The study was performed on 18 infants: PN from premature birth (PB) (n=6); PN from early preterm birth (EPB) (n=6); PN from a very early preterm birth (VEPB) (n=6). The EPO used in concentrations of 30 IU/l; 15 IU/l; 7,5 IU/l; 3,75 IU/L. Evaluated the absorption capacity and oxygen-dependent metabolism of neutrophils isolated from umbilical cord blood. Have PN from EPB and VEPB, EPO in in vitro experimental conditions increases, and PN from PB - reduces the absorption capacity and NBT-reducing capacity of blood neutrophils. EPO effect on the absorption capacity of blood neutrophils in in vitro experimental conditions does not depend on gestational age and manifests itself in small doses (3,75 IU/l and 7.5 IU/l), and NBT-reducing capacity of blood neutrophils in large doses (15 IU/l and 30 IU/l).
